ROKR Song Limit Upgrade via iTunes?
While exploring the iTunes 6.0.3 binary file, Evan DiBiase found mysterious references to "upgradePhone" which eventually led to an iTunes screen offering an upgrade to the ROKR, for a price.
It's since been confirmed that the upgrade only applies to ROKR owners in Asia, whose phones only hold 50 songs. The upgrade only boost the song count to...yup, 100 songs. Ah well.
